LIQUID-LENDING MACHINE.

Application filed October 22, 1924. Serial No. 745,178.

This invention relates to a liquid-vending machine, having moreparticular reference to a machine for use in dispensing or vending softdrinks. 1

The invention has for an object to provide a novel and improved machineof this type, arranged for delivering a cup, a concentrated flavoringextract, and filtered water, the. flavoring extract being afterwardplaced in the cup and the latter filled with the filtered water. i

For further comprehension of the invention, and of the objects andadvantages thereof, reference. will be had to the follow ing descriptionand accompanying drawing. and to. the appended claims in which thevarious novel features of the invention are more particularly set forth.

Fig. 1 of the drawing is aface view of my improved vending machine.

Fig. 2 is a vertical sectional view thereof, taken on the line 2-2 ofFig. 1.

Fig. 3 is a detail horizontal sectional view taken on the line 3-3 ofFig. 2.

Fig. 4 is a face view of the package con taining the concentratedflavoring extract.

Fig. 5 is a face view of the blank from which the envelope of thepackage is made.

Fig. 6 is a detail View of a plunger and its co-operating parts.

In the drawing the reference numeral 10 indicates the lower part of acup vending machine of the type adapted to deliver paper cups, theupwardly projecting glass maga- Zine being shown at 11. This casing isformed with the usual slot 12 to receive the coin that releases thedelivery mechanism. buitably mounted on a common frame 13 with the cupvending device, and spaced laterally from the same, is a vending machine of the usual type arranged to deliver small flat packages, thismachine being indicated generally at 14 and being provided with theusual coin-controlled ejecting mechanism.

Located between these two devices is a liquid delivering element that iscontrolled by the operating element of the cup delivering device. Thisliquid delivering device comprises a casing 18 having an aperture in thebottom thereof surrounded by a. depending flange 19 this aperturereceiving a receptacle or cup 20 that projects below the bottom of thecasing, and is provided substantially midway between its. top and bottomwith a filtering member 21 that extends in the form of a horizontalpartition thereacross. At its upper end this cup is provided with aradially projecting flange 23 that is supported by a number ofbow-springs 24 attached to the underside thereof and resting on the bottom of the casing, thereby yieldingly supporting the cup.

Leading into the casing 18, through the back thereof, is a water supplypipe 25 that has its end downturned toward the cup 20 to deliver waterinto the latter. This pipe is controlled by a valve 26 of the ordinaryrotary plug type, whose plug 27 has fixed to one end thereof anelliptical arm 28 having pivoted on its free end a latch 29 that acts tohold the valve in open position. This latch engages a pin 30 projectingfrom an abutment arm 31 that is pivoted at its upper end as at 32 in thecasing and hangs downward therein. The latch 29 is urged outward to enage the pin by means of a spring 33 attac ied at one end theretoand atits other end to the arm 28, while a tail-piece 29 on the latch engagesstud 34 fixed to the said arm to limit outward movement of the latch.Attached at one end to the abutment arm 31 and at its opposite end to arod 35 fixed in the casing walls is a tension spring 36 that normallyurges the said arm in a direction to free the pin 30 from the latch 29.I The abutment arm 31 is normally held against movement under theinfluence of the spring 36 by means of the flange 23 on the cup 20. Thisflange is engaged by a plunger 40 slidable in a longitudinal boring inthe said arm entered thereinto from the lower end thereof, an'expansionspring 41 being located in the said boring above the plunger to urge thelatter downward, while downward movement is limited by means of a pin 42extending transversely through the plunger into short vertical slots 43in the said arm 31. The lower end of the arm 31 is bevelled off as shownat 45 to form a cam surface on which the flange 23 on the cup 20 bearsto swing said arm at certain-times. Swinging movement of the arm 31 islimited by means of the rods 46 and 47 fixed to the walls of the casingand projecting one on each of the arm. The plug 27 of the valve 26 hasfixed to its other end an operating arm 50, that is positioned outsidethe casing 18 and is connected by a rigid bar 51 with the ejectingelement of the cup vending element, a knob 52 being fixed to this arm.The arm is retained in normal position by a spring 53.

The package containing the concentrated flavoring is shown in Fig. 4; ofthe drawing and is in the form of a flat carton formed from a blank 55.In this carton I may place a liquid flavoring in a capsule 56, or a dryflavoring, and a powder 57 to cause effervescence.

In the operation of my improved vending device the user places a coin inthe vending element 14: and receives a package containing the flavoringextract, which may be lemon or any other that is desired. A second coinis then placed in the slot 12 of the cup vending element and knob 52 ispulled, both delivering a cup from the magazine 11 and opening the valve26. When the valve moves to open position the latch 29 rides under thepin 80 and retains the valve open. The Water then flows through the pipe25 and when the proper quantity has collected in the cup 20 theincreased weight of cup causes the springs 24: to be compressed and thecup to drop su'lii ciently to lower the flange below the plung er %O.The arm 31 then swings, under the influence of spring 36, to free thepin 30 from the latch 29, allowing the valve to be closed by the spring53. This spring also acts to return the cup delivery element to itsnormal position. A delivery cock 60 in the cup 20 is then opened and thefiltered Water allowed to flow into the paper cup that has been receivedfrom the magazine 11, the concentrated flavoring extract being placed inthis cup. When the cup 20 is lightened by the discharge of the watertherefrom the springs 24 urge it upward. As the cup moves upward theflange 23 bears on the bottom of the plunger 40 and moves the latterupward, the flange 23 engaging also the bevelled lower end 45 of the arm31 and swinging the same to one side until the plunger 40 springsdownward again beside the said flange. The flavoring extract may bedelivered to the cup 20 through a tube 61.

Having thus described my invention, what I claim as new and desire toprotect by Letters Patent of the United States is as follows 1. In avending machine, a liquid delivery pipe, a valve controlling said pipe,a lever for operating said valve, a niovabiy mounted cup for receivingthe liquid from said pipe, and a latch element controlled by said cupfor holding the said valve open.

2. In a vending machine, a liquid deliv ery pipe, a valve controllingsaid pipe, a lever for operating said valve, a yieldingly supported cupfor receiving the liquid from said pipe, a latch element on said valvefor holding the same open, and an abutment arm engaged by said latchelement, said abutment arm being retained in operative position by thesaid cup when the latter is empty.

3. In a vending machine, a liquid delivery pipe, a valve controllingsaid pipe, a lever for operating said valve, a yieldingly supported cupfor receiving the liquid from said pipe, a latch element on said valvefor holding the same open, and an abutment arm engaged by said latchelement. said abutment arm being retained in operative position by thesaid cup when the latter is empty, said abutment arm having a plungerslidable in the free end thereof engaged on its side by the said cup,the lower end of said abutment arm being bevelled to form a cam surfaceon which said cup rides to swing the said abutment arm laterally whenthe cup moves upward after discharge of the liquid therefrom.

In testimony whereof I have atiixed my signature.
